A little bit more on this subject about inks. I was explaining to my youngest son, who is an archaeologist, about my printer problem, and he pointed out that cheap inks do not provide long-term stability for hard-copy photographs. Canon inks are guaranteed to be stable and provide archive quality for up to one hundred years. This is important if, like us, you are producing hard copy photos for your family to keep and pass on down through the family archive. So what I intend to do is to purchase the MG5250 and. once installed and running, repair the head of my existing MG5350 and then fit one with Canon inks for archive photos and the other with cheap inks for day-to-day stuff. Incidentally, after the last clean, the 5350 has worked perfectly.
